Emirtech Technology is an ADMCC-approved electronic security contractor founded in 2018, operating from M44, Mussafah Industrial Area, Abu Dhabi, and we deliver phased Wiegand-to-OSDP migrations across Abu Dhabi and Al Ain on a reader-by-reader basis with minimal downtime. Legacy Wiegand 26-bit and 32-bit wiring is unencrypted and unidirectional — credentials travel as clear binary pulses vulnerable to credential sniffing and replay attacks via tools such as the ESPKey, cable runs are typically capped near 150 m, and panels receive no reader-status feedback, tamper alerts or firmware-update path. OSDP (Open Supervised Device Protocol, SIA-standardised) resolves each weakness with AES-128 Secure Channel encryption, bidirectional RS-485 messaging, multi-drop support for several readers on one cable, run lengths up to 1,200 m, and over-the-wire firmware updates. We configure OSDP v2.2 on native-capable hardware: HID Multi-Class SE and Signo readers, Mercury Security intelligent controllers (LP1502 / LP4502), ZKTeco ProMA / SpeedFace OSDP variants, Suprema BioStation / X-Station 2, and head-end integrations with LenelS2 OnGuard, Software House C-CURE 9000, and Honeywell Pro-Watch. Typical sequence: site survey of existing Wiegand topology, controller firmware baseline, OSDP install-mode pairing with Secure Channel Base Key (SCBK) rotation, supervised commissioning, and decommissioning of unsupervised Wiegand tails. Migrations can be prompted by insurer requirements, audit findings or enterprise security uplift programmes; where a client's procurement clauses reference NDAA-style hardware restrictions, those are separate from OSDP itself and are confirmed against the clause wording. We install and programme Control4 working with a third-party authorised dealer. We are not an Authorised Distributor, Channel Partner or Master Dealer of HID Global, Mercury Security, ZKTeco, Suprema, LenelS2, Software House or Honeywell, we are not a HID Mobile Access Premier Partner, and we are not a member or representative of the Security Industry Association (SIA), which is the OSDP custodian. We install commercially through authorised UAE channels; we are not SIRA-Dubai licensed and we operate ADMCC-regulated work in Abu Dhabi and Al Ain only.

Migration Capabilities
Site survey of existing 26/32-bit Wiegand readers, cable runs, panel ports, tamper loops and door hardware — documented per-door schedule confirming which readers are OSDP-capable in-place and which require replacement before phased migration.
OSDP v2.2 install-mode pairing with Secure Channel Base Key (SCBK) rotation, encrypted RS-485 messaging configured on HID Signo, Mercury LP-series, ZKTeco and Suprema readers, and supervised tamper / status reporting verified end-to-end.
Re-cabling or re-terminating to support up to four OSDP readers per RS-485 trunk with runs up to 1,200 m, biased and terminated correctly, replacing point-to-point Wiegand home runs for materially lower cable and containment cost.
OSDP reader binding to LenelS2 OnGuard, Software House C-CURE 9000, Honeywell Pro-Watch or Mercury-native panels — credential format mapping, cardholder migration and reader LED / buzzer feedback configured and acceptance-tested.
Door-by-door OSDP migration with documented Secure Channel keys, supervised commissioning, and acceptance handover. For a site walk and migration scoping across Abu Dhabi or Al Ain, call +971 55 651 7843 or request a free Wiegand-to-OSDP migration consultation.
Why upgrade from Wiegand to OSDP
Wiegand pulses are clear and trivially captured with ESPKey-class implants between reader and panel. OSDP Secure Channel applies AES-128 to every message, removing the credential-replay attack surface that drives insurer and audit findings.
OSDP reports reader online status, tamper, power and firmware revision back to the head-end in real time, replacing the silent-failure mode of Wiegand where a removed or sabotaged reader is only detected via cardholder complaints.
Multi-drop RS-485 carries several readers on a single trunk up to 1,200 m, materially reducing containment, cable and labour cost on large Abu Dhabi industrial and warehouse footprints compared with point-to-point Wiegand.
Some enterprise tenants write NDAA-style hardware restrictions into their procurement clauses. NDAA Section 889 itself targets specific telecommunications and video-surveillance vendors and is separate from OSDP, so the clause wording is confirmed first; where hardware origin matters, an OSDP migration to HID Signo, Mercury or Suprema platforms can be scoped without ripping out the entire access control system.
Emirtech Technology delivers the technical migration layer: survey, hardware replacement, OSDP Secure Channel configuration, head-end integration and acceptance testing. We are transparent about the brand and regulator relationships we do not hold, so procurement and audit teams can scope correctly.
Scope is fixed in writing before any reader is replaced — a per-door schedule, OSDP address plan, Secure Channel key custody procedure and acceptance criteria. That keeps the upgrade auditable and avoids partial-supervision states during the migration window.

Common questions
Wiegand 26/32-bit is an unencrypted, unidirectional pulse protocol from the 1980s with cable runs typically under 150 m and no reader-status feedback. OSDP is an SIA-standardised RS-485 protocol that adds AES-128 Secure Channel encryption, bidirectional supervision, multi-drop wiring up to 1,200 m, and over-the-wire firmware updates. The change closes the credential-sniffing and silent-failure gaps that commonly appear in access control audit findings.
We configure OSDP v2.2 on HID Multi-Class SE and Signo readers, Mercury Security LP1502 / LP4502 intelligent controllers, ZKTeco ProMA / SpeedFace OSDP variants, and Suprema BioStation / X-Station 2. Head-end integrations include LenelS2 OnGuard, Software House C-CURE 9000, Honeywell Pro-Watch and Mercury-native platforms. Brand selection is driven by the existing head-end, NDAA requirements and credential format.
Not directly. We hold no manufacturer-level credential of our own. We are not an Authorised Distributor, Channel Partner or Master Dealer of HID Global, Mercury Security, ZKTeco, Suprema, LenelS2, Software House or Honeywell, and we are not a HID Mobile Access Premier Partner. We install and configure commercially via authorised UAE distribution channels. We are also not affiliated with the Security Industry Association (SIA), which custodies the OSDP standard.
Not directly. Emirtech is ADMCC-approved and delivers ADMCC-regulated electronic security work in Abu Dhabi and Al Ain only. In Dubai, CCTV, alarm and access control are delivered through SIRA-approved partners, with Emirtech coordinating. Wiegand-to-OSDP migrations are scoped within our Abu Dhabi and Al Ain coverage area.
Yes — that is the standard approach we use. Mercury, LenelS2 and C-CURE controllers support mixed Wiegand and OSDP ports concurrently, so doors are converted one or two at a time during agreed maintenance windows. Each door is commissioned, Secure Channel keys are rotated, the reader is acceptance-tested under live cardholders, and the unsupervised Wiegand tail is decommissioned before moving to the next door.
Call +971 55 651 7843 or email [email protected] from M44, Mussafah Industrial Area, Abu Dhabi, or use the emirtech.ae/request-quotation.html form. We arrange a site survey, produce a per-door reader and panel schedule, confirm OSDP v2.2 compatibility, and return a fixed-scope migration proposal with phasing, Secure Channel key custody, acceptance criteria and as-built documentation.
